U tube lab glass, Nairobi Industrial Area

U-tube lab glass, also known as a U-tube manometer, is a glass device shaped like the letter “U” that is primarily used for measuring pressure in gases and liquids. It consists of two vertical arms connected at the bottom, typically filled with a liquid (like water or mercury) that acts as a pressure reference. The difference in height between the two liquid columns indicates the pressure difference between the two points being measured.
